Liquid crystal display device and method of fabricating the same

Abstract

An LCD device includes first and second substrates, an alignment layer formed over at least one of the substrates, and a liquid crystal layer formed between the substrates. The alignment layer is formed of a mixture of rubbing alignment and UV alignment materials. A method of fabricating the LCD device includes preparing first and second substrates; coating an alignment layer over at least one of the substrates; performing a rubbing process on the substrate coated with the alignment layer; and irradiating polarized UV rays onto the substrate coated with the alignment layer, wherein the alignment layer is formed of a mixture of rubbing alignment a UV alignment materials. The rubbing process obtains high anchoring energy is obtained, thereby preventing afterimages. Also, the process of irradiating the polarized UV rays eliminates the problem of light leakage.

AI Technical Summary

Benefits of technology

The invention aims to solve issues with both the rubbing alignment method and the photo-alignment method in LCD devices. The technical effect is to provide a more reliable and effective way of aligning the components of an LCD device during fabrication.

Problems solved by technology

The technical problem addressed in this patent text is to develop a method for aligning liquid crystals in LCD devices that does not require physical contact between the substrate and does not cause afterimages. The current rubbing alignment method and photo-alignment method have limitations in controlling the alignment of liquid crystals and may cause light leakage or afterimages. A new method is needed to overcome or minimize these issues.
